A quintessence scalar field with a constant-equation-of-state potential
Hoavo Hova
In this paper we study a quintessence scalar field in a potential exponentially decreasing with e-folding number, and show that the universe is currently undergoing an accelerated…

crossing in quintessence models in Lyra's geometry
Hoavo Hova, Huanxiong Yang
We study the cosmology of quintessence models in an extended theory of gravity in Lyra's geometry. By analyzing the possible interactions between the quintessence scalar and the in…

A dark energy model alternative to generalized Chaplygin gas
Hoavo Hova, Huanxiong Yang
We propose a new fluid model of dark energy for as an alternative to the generalized Chaplygin gas models. The energy density of dark energy fluid i…
